Computing spyndex indices

[guillemc23]

I'm having a bit of trouble when computing indices from the Spyndex catalog for a Sentinel 2 product. Is there any example? I couldn't find them in the docs and I got a bit confused with EOReader indices and how they differ from the Spyndex ones 🤔

For example, I was able to replicate the example with the NDWI, but I'm unable to do the same with NBR

I was having namespace issues, this should work as expected:

from pathlib import Path

from eoreader.bands import BLFEI, NBR, NBR2, NDVI, NDWI, UI
from eoreader.reader import Reader


def main():
    product_path = Path("S2A_MSIL2A_20240716T100601_N0510_R022_T33TUM_20240716T160254.SAFE")

    reader = Reader()
    prod = reader.open(product_path=product_path)

    ndwi = prod.stack(NDWI, stack_path="NDWI.tiff")
    ndvi = prod.stack(NDVI, stack_path="NDVI.tiff")
    ui = prod.stack(UI, stack_path="UI.tiff")
    blfei = prod.stack(BLFEI, stack_path="BLFEI.tiff")
    nbr = prod.stack(NBR, stack_path="NBR.tiff")
    nbr2 = prod.stack(NBR2, stack_path="NBR2.tiff")

if __name__ == "__main__":
    main()

Still I believe the docs have some outdated examples on this matter because of the old "EOReader Indices" vs "Spyndex Indices" :)
